High- and low-end happily coexist every summer at Hewtin's Dogs, chef Matt Gennuso's gourmet hot dog cart. Gennuso treats the side endeavor with as much care and enthusiasm as the upmarket French restaurant he owns across the street, topping all-beef Grote and Weigel franks with homemade condiments like spiced tomato preserve, Vidalia onion relish, and sauerkraut made from cabbage braised in duck fat. The result is one haute dog. Hewtin's Dogs, Lippitt Park, across from 960 Hope Street, Providence, 401-421-4422, chez-pascal.com.
